When heated, lithium reacts with nitrogen to form lithium nitride:
|6Li(s) + N2(g)
What is the theoretical yield of Li3N in grams when 12.1 g of Li is heated with 33.0 g
If the actual yield of Li3N is 6.33 g, what is the percent yield of the reaction?
Mass of Li = 12.1 g
Mass of N = 33 g
What is the theoretical yield of Li3N?
Find the moles of Li and N2 :
Moles of Li = 12.1 / 6.9 mol = 1.7 mol.
Mol. Of N2 = 33 / 28 = 1.1 g
Observe the balanced equation,
6Li(s) + N2(g)→ 2Li3N(s)
As per the balanced equation above, 6 moles of Li react with 1 mol. Of N,
1.7 mol. Of Li needs --------? Mol. Of...
